c7ba4828b1 Slight reorganisation of the Alpha/SRM loader build:
- Make as much of the makefile for each of the three flavours
   (disk, CDROM, net) common.
 - Special-case the libalpha startup module on its use in boot1, not
   the other way around.
 - Build the loader out of a "loader" directory

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

06feb69276 * Extend the memory available for the heap from 256k to 512k.
* Embed the stack into the bss section for loader and netboot.  This
  is required for netboot since otherwise the stack would be inside our
  heap.
* Install loader and netboot in /boot by default.
* Fix getbootfile so that it searches for a ',' instead of a ';'
  when terminating the filename.

pool.

e24168e6c3 * Add old UFS compatibility code to alpha/boot1.
* Fix a raft of warnings, printf and otherwise.
* Allocate the correct amount in mod_searchmodule to prevent an overflow.
* Fix the makefiles so they work outside my home directory (oops).

2b5cfb37f7 Minor tweaks to track a couple of i386 changes and to make it compile. 1998-08-22 10:31:01 +00:00

c2f9d95de5 This is the new unified bootstrap, sometimes known previously as the
'three-stage' bootstrap.
There are a number of caveats with the code in its current state:
 - The i386 bootstrap only supports booting from a floppy.
 - The kernel and kld do not yet know how to deal with the extended
   information and module summary passed in.
 - PnP-based autodetection and demand loading of modules is not implemented.
 - i386 ELF kernel loading is not ready yet.
 - The i386 bootstrap is loaded via an ugly blockmap.

On the alpha, both net- and disk-booting (SRM console machines only) is
supported.  No blockmaps are used by this code.
